The three rules that apply to every stain
Act immediately. Every minute a stain sits in fabric, it sets further. Fresh stains are dramatically easier to remove than dried ones. The best stain remover in the world is speed.
Blot, never rub. Rubbing a stain spreads it laterally, pushes it deeper into the fibre, and damages the fabric surface. Press down firmly with a clean cloth or paper towels and lift. Repeat with a fresh section of cloth each time. Work from the outside of the stain inward to avoid spreading.
Extract, don’t surface clean. A spray and wipe moves the stain around and dilutes it into the surrounding fibre. Extraction (injecting cleaning solution and pulling it back out) removes the stain from the fibre. For carpet and upholstery stains that matter, a spray extraction machine is the correct tool.

Red wine
Red wine contains tannins and pigments that bind strongly to carpet and fabric fibres. The common advice to pour white wine or salt on the stain is largely ineffective — white wine dilutes the stain slightly and salt absorbs some surface liquid, but neither extracts the pigment from the fibre.
Fresh red wine:
Blot immediately with paper towels. Press firmly and replace as they become saturated. Remove as much liquid as possible before introducing any cleaning solution. Apply diluted VTC420 to the stain and allow to dwell for three to five minutes. Extract with the SPRAYEX carpet head or upholstery attachment. Repeat until the extracted water runs light. The stain will lighten significantly and may disappear entirely on the first treatment if addressed quickly.
Dried red wine:
Rehydrate the stain first by applying warm water and allowing it to dwell for five minutes before applying the cleaning solution. Dried tannin that has crystallised in the fibre needs to be dissolved before it can be extracted. Apply diluted VTC420, allow 10–15 minutes dwell time, agitate gently with a soft brush, extract. Multiple passes will be needed. Dried red wine on pale carpet or upholstery may leave a permanent shadow even after thorough treatment — particularly on wool or natural fibre carpets.
Coffee and tea
Coffee and tea stains contain tannins like red wine but at lower concentration, making them generally easier to remove. The key variable is milk - milky coffee or tea leaves a protein residue in addition to the tannin, which requires the cleaning solution to address both simultaneously.
Fresh coffee or tea:
Blot immediately. Apply diluted VTC420 and dwell three minutes. Extract. For milky coffee, a second application and extraction pass is usually needed to address the protein residue. The stain should come out completely if addressed while fresh.
Dried coffee or tea:
Apply warm water to rehydrate, then diluted VTC420 with 10 minutes dwell time. Extract. The brown staining from dried coffee responds well to extraction treatment and rarely leaves a permanent shadow on most carpet types.
Grease and cooking oil
Grease and oil stains do not respond to water-based cleaning alone — oil and water repel each other. You need a degreasing agent that emulsifies the grease so it can be suspended in water and extracted.
Fresh grease or oil:
Do not apply water immediately. First, apply an absorbent powder - bicarbonate of soda or cornflour - to the grease spot and leave for 10–15 minutes to absorb surface oil. Brush or vacuum away the powder. Then apply diluted VTC420 (which contains surfactants that emulsify oil) and allow to dwell for five minutes. Extract with the SPRAYEX. The extraction will lift the emulsified grease from the fibre.
Dried grease:
Dried grease has oxidised into the fibre and is harder to remove. Apply diluted VTC420 and allow 15–20 minutes dwell time to allow the surfactants to penetrate the oxidised grease. Agitate gently with a brush. Extract. A second treatment is often needed. Very old grease stains on pale carpet may leave a yellowed shadow even after thorough treatment.
Mud and soil
The most common mistake with mud is cleaning it while wet. Wet mud spreads across a much larger area and is driven deeper into the fibre by cleaning attempts. Always allow mud to dry completely before cleaning.
Allow to dry first. Once dry, break up the dried mud with your fingers and vacuum as much as possible. Remove the dry surface material before introducing any liquid.
Apply diluted VTC420 and allow three to five minutes dwell time. Extract. Mud is generally straightforward to remove once the dry material has been removed - the residual brown staining in the fibre extracts well.
Blood
Blood contains protein that sets permanently in heat. Never use hot water on a blood stain. Cold water only.
Fresh blood:
Blot immediately with cold water and a clean cloth. Remove as much surface blood as possible. Apply diluted VTC420 (cold) and dwell three minutes. Extract with cold extraction. Fresh blood on most carpet types will come out completely.
Dried blood:
Rehydrate with cold water only and allow to dwell for 10 minutes before applying cleaning solution. Dried blood that has set into carpet fibre is significantly harder to remove and may require multiple treatments. Never apply heat at any stage as heat permanently sets protein stains.
Ink
Ink stains vary significantly by ink type. Ballpoint pen ink is oil-based and responds to isopropyl alcohol applied with a cloth before extraction cleaning. Fountain pen and printer ink is water-based and responds better to direct extraction with diluted VTC420.
For ballpoint ink: apply a small amount of isopropyl alcohol (surgical spirit) to a clean cloth and blot the stain - do not pour directly onto the carpet. The alcohol dissolves the oil-based ink. Follow immediately with diluted VTC420 and extract. Work quickly as alcohol evaporates fast.
For water-based ink: apply diluted VTC420, dwell five minutes, extract. Multiple passes needed for dense ink marks.
Candle wax
Candle wax must be removed in two stages: solid removal first, then residual cleaning.
Allow the wax to harden completely - do not attempt to remove liquid wax. Once hard, carefully break and lift as much solid wax as possible. For carpet, place a piece of plain brown paper or a white cloth over the remaining wax and apply a warm (not hot) iron briefly - the wax melts and transfers to the paper. Repeat with fresh paper until no more wax transfers.
Apply diluted VTC420 to the remaining residue and extract. Any dye from coloured candle wax will require the same treatment as a fabric dye stain.
General Food Stains
Most food stains like tomato sauce, curry, fruit juice, and chocolate, follow the same approach: remove solid or excess liquid first, then extract with diluted VTC420.
Curry and tomato: High in natural pigments (turmeric, lycopene) that stain aggressively. Blot immediately, remove solid material, apply VTC420 with extended dwell time (10–15 minutes), extract. Pale carpet or upholstery may retain a yellow shadow from turmeric even after thorough extraction - this is one of the most persistent natural pigments.
Chocolate: Allow to harden if melted, then scrape off solid material. Apply VTC420, dwell five minutes, extract. Chocolate stains respond well to extraction treatment.
Fruit juice: Treat like red wine - blot immediately, apply VTC420, extract. Dark fruit juices (blackcurrant, blueberry) are the most persistent.
Fabric dye and hair dye
Fabric dye and hair dye that has transferred to carpet or upholstery is one of the hardest stain types to remove. The dye is designed to permanently colour fibre - it will colour carpet and upholstery fibre in exactly the same way.
Act immediately. Apply diluted VTC420 and extract before the dye sets. The window for effective treatment is very short - often minutes rather than hours. Once set, professional cleaning or colour restoration by a specialist may be required for pale carpets. Accept that some dye transfer stains will not fully resolve with home treatment.
When extraction is not enough
Some stain types, stain ages or fabric combinations will not fully resolve with home extraction cleaning. Indicators that professional treatment is needed:
- Pale or white carpet with pigment staining (turmeric, red wine, fabric dye) that persists after two full extraction treatments
- Any stain that has been treated with the wrong method first — rubbed, treated with bleach, or subjected to heat
- Natural fibre carpets (wool, silk, sisal, coir) with heavy staining - these require specialist treatment
- S-coded upholstery fabrics that have been wet-cleaned - these cannot be safely cleaned with water-based extraction at home
Annual extraction clean prevents most stain problems
A carpet or upholstery surface that is regularly extraction cleaned is significantly harder to stain permanently than one that has only been vacuumed. The extraction process removes the accumulated soil, oils and residue in the fibre that acts as a binding agent for new stains. Clean fibre releases new stains far more readily than soiled fibre.
